Great video, thanks! Glad I came here in addition to ChrisFix's video or else I would have ended up using a chemical flush and probably regretted it.

[@NewRoad]

Glad it helped!

[@Encourageable]

I have a 2016 Colorado diesel. There’s a petcock - and it’s refilled through the reservoir. Mine was so easy.

[@NewRoad]

I guess it's called progress 🙂. Hummer H3 is 2005 technology 😀

[@carterhensley2478]

Best descriptive video by far

[@NewRoad]

Glad it was helpful!

[@IamFreeRu]

Thank you very much for this video. Just did a coolant flush and replaced coolant on hummer H3.

[@NewRoad]

Glad it helped

[@bethanydavenport843]

Ok so 50/50 is cool to use when my antifreeze and coolant are superset in the same hummer h3 2006

[@dhilipembedded]

Excellent video! How much do we need to buy for H3? Is it 5 Liters is enough?

[@alerumba]

Hi .. I know this question doesn’t belong in this video.. but since you don’t have “ didn’t find “ a video for power steering.. do you know what fluid type of power steering is for Hummer h3 2007? I looked but can’t see any answer online.. I want a oem fluid.. thank you for keep saving me with your videos!

[@NewRoad]

Here is the video how to change power steering fluid in H3: kzbin.info/www/bejne/fXSuq3Z4gsx1bpY I used this fluid: amzn.to/3u6BsrO

@@NewRoad Thank you!!!!

[@vashdstampede416]

What if my heater doesn't work?????

[@rvingchub]

My 2016 Canyon doesn’t have a radiator cap. How do you refill with coolant?

[@nou3796]

I have a 17 model, it's going to be filled by the coolant overflow tank, passenger side if it's the same style of engine bay.

[@AustinDollMusic]

Where can I buy that fluid? lol can’t find it anywhere in stock near Detroit

[@NewRoad]

I usually buy from rockauto.com

[@DIZEMANPHOTO]

My question is, why are you warning not to use a chemical flush? What is the basis for that warning?

[@NewRoad]

That is not mine - that is a warning from GM in their service manual for 'Cooling System Draining and Filling' procedure for H3. I didn't have much time to find specific reason why they do not recommend to use chemical flush. Generally, I always recommend to follow what car manufacturer prescribe 😊

[@DIZEMANPHOTO]

@@NewRoad Thanks, I did some research and sure enough, it says DO NOT USE CHEMICAL CLEANER, by that I assume they mean like Prestone Coolant Flush or that sort of thing.

[@paulwood9043]

I have a 2007 chevy colorado truck with a 5 cylinder engine and I am going to drain the old antifreeze off and put dexto premixed antifreeze fluid in it, so when I drain all the old antifreeze off will there be some leftover in the engine? and if so how do I get that out, do I need to flush again as of cold water?

[@NewRoad]

It's in this video, I showed how I flushed it. Make sure you use Distilled water

[@RainsMobileMechanic]

I drained it from the lower radiator hose but no coolant left the over fill reservoir?? Is that an issue

[@NewRoad]

No, since you will flush it again... if you watched the video until the end

[@UnionMoney510]

How do I get the reservoir to drain fully

[@NewRoad]

You will have to flush it few times

[@Thinker669]

How many gallons of coolant.

[@NewRoad]

10.0 qt / 9.5L -> 2.51 gallons

[@nopenope414]

Why not unscrew the drain plug?

[@NewRoad]

There is no drain plug

[@nopenope414]

@@NewRoad I have a 2017 GMC canyon do you know if that one has?thanks

[@NewRoad]

@@nopenope414 I am not sure, just search it on net or get under the truck and check

[@hebertjessedparramoreno2114]

Nice video man, i will do it in my Hummer h3 🔥

[@IamFreeRu]

Isn't it bad to drive the car with just distilled water for 30 minutes?

[@NewRoad]

No, since you gonna replace it with proper mix at the end

[@victorgonzalez7027]

I don't know!! There must be another way to do it.

[@30guarino]

you can take it to the dealer..... and bring extra cash

[@jerrypond7946]

what no voice???

[@NiceCarsLover]

No petcock on these. So cheap! And it makes a mess.

[@hasrilacci981]

buntu buntu

[@Captaintripps1]

Dexcool is so bad on your engine eats up your seals and Gaskets...i drained all my dexcool out and put regular antifreeze for all makes and models and it works good for a over a year now

[@NewRoad]

It works for me :-)

[@al44dmich99]

Don’t know how your treating your car🤧 my Colorado has had dexcool it’s at 181k miles🤷‍♂️

[@DIZEMANPHOTO]

Captain Tripps You are perpetuating misinformation based on a problem that existed when Dexcool was introduced. The problem was not the Dexcool itself, but instead it was the composition of the intake manifold gasket, which has been replaced with a more resilient gasket material in all late model cars, older than 2001. The only time Dexcool causes issues in cars later than 2001 is when air is introduced into the coolant chambers within the engine and along with the acidic component of the coolant and the air, corrosion of some gaskets can occur. The part nobody tells you is that allowing air into the coolant chambers will cause oxidation and some sensor failures with ANY COOLANT, NOT JUST DEXCOOL. If you maintain your coolant on regular basis, change out and flush every couple of years or so, keep your coolant topped off and never allow leaks to continue for long periods of time which allow air into the system, never run coolant low enough to allow air into your system and ALWAYS BURP the air out of your entire coolant system when changing your coolant, the Dexcool will serve cars that require Dexcool longer and more effectively than cars that do not recommend Dexcool. You're perpetuating a rumor that no longer applies, except under certain conditions, like owner negligence, not maintaining the coolant system properly and blaming it on Dexcool. My 2007 Hummer H2 has had the same Dexcool, listed as REQUIRED in the manual for 12 years/140,000 miles, has NEVER been changed, the truck has NEVER run hot and there are no signs of issues. I am changing the Dexcool and flushing my entire system tomorrow (7/2/2020) and will be refilling the system again with Dexcool. I anticipate if the truck performs as it has the past 12 years, it just might out live me. If you don't want to use Dexcool, then don't, but spreading false rumors based on decades old information is disingenuous. The problem is not Dexcool, the problem is Dexcool and AIR in your water system. Burp your water chambers properly and Dexcool is, well... COOL!

[@henrymallett6847]

Dexcool is GM recommended
